Support Rails
Support rails provide stability over the entire length of shaft and eliminate bending under moderate to heavy loads. Made of lightweight, corrosion-resistant aluminum, they are designed for use with linear shafts and bearings. Cut to size or mount end-to-end to make longer lengths. Mounting holes match those on our Shafts for Support Rails; attach using socket head screws (not included).

Low-Profile Support Rails
At approximately one-third the height of standard versions, these rails provide linear shaft support in applications with low vertical clearance. They provide stability over the entire length of shaft and eliminate bending under moderate to heavy loads. Made of carbon steel or lightweight, corrosion-resistant aluminum, they are designed for use with linear shafts and bearings. Cut to size or mount end-to-end to make longer lengths.
Rails with mounting holes match those on our Shafts for Support Rails; attach using socket head screws (not included).
